A receiving device (e.g., user equipment (UE)) may receive a configuration for full-duplex communication resources for a set of time slots from a transmitting device (e.g., a base station). The receiving device may receive a preemption indication that identifies that at least a portion of the full-duplex communication resources in one or more time slots in the set of time slots are not available for communication, and may determine a remaining portion of the full-duplex communication resources in the one or more time slots based on the received preemption indication. The receiving device may then use the remaining portion of the full-duplex communication resources to communicate with the transmitting device.

[0002] This patent application claims the benefit of Greek Provisional Patent Application No. 20200100057, entitled “PRE-EMPTION INDICATION FOR FULL DUPLEX COMMUNICATIONS,” filed by ABOTABL et al. on February 4, 2020, which is assigned to the assignee of this application and is expressly incorporated herein. Technical Field

[0003] The present disclosure relates generally to wireless communications and, more particularly, to preemption indication for full-duplex communications. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, and the like. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include: fourth generation (4G) systems, such as long term evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems, which may be referred to as new radio (NR) systems. These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include multiple base stations or network access nodes, each of which simultaneously supports communication with multiple communication devices, which may be further referred to as user equipment (UE).

[0005] Some wireless communication systems may support UEs or base stations capable of full-duplex communication (e.g., transmitting and receiving simultaneously). In some cases, a full-duplex wireless device may be affected by interference from the device's own signal transmission and reception, which may sometimes be referred to as self-interference. In particular, when a UE is receiving on a downlink, its antenna may be interfered with by a signal sent on an uplink by the same UE. In addition, a full-duplex wireless device may be interfered with by a downlink signal while sending an uplink signal. In other cases, a full-duplex base station may transmit to one or more UEs on a downlink, which may cause a certain degree of interference to the uplink signal received by the base station when it is transmitting. Therefore, improved techniques may be needed to improve communication efficiency in full-duplex wireless devices. Summary of the invention

[0006] The described technology relates to an improved method, system, device and apparatus for supporting preemption indication for full-duplex communication. In general, the technology is used to configure full-duplex communication to reduce or minimize resource usage. In some aspects, a user equipment (UE) may identify one or more radio frequency (RF) spectrum bands configured for full-duplex communication. The UE may communicate with a base station based on one or more full-duplex communication types supported by the UE. In some cases, the UE may receive a full-duplex preemption indication, which indicates a downlink preemption indication or an uplink preemption indication or both. As an example, a base station may send a configuration of full-duplex communication resources for the UE for a time slot set to the UE. In order to indicate a downlink preemption indication and an uplink preemption indication for a time slot set configured with full-duplex communication resources, the base station may signal the UE with a full-duplex preemption indication. According to one or more aspects, the UE may receive a full-duplex preemption indication, and may identify downlink preemption resources and uplink cancellation resources based on the full-duplex preemption indication. The UE may then determine a remaining portion of the full-duplex communication resources and may use the remaining portion of the full-duplex communication resources to communicate with the base station.

[0046] Some wireless communication systems may support full-duplex communication for various wireless devices in the system. For example, both the user equipment (UE) and the base station are capable of transmitting and receiving simultaneously. Therefore, the radio frequency spectrum band may be configured to support full-duplex communication. For example, a radio frequency spectrum band configured for, for example, time division duplex (TDD) operation may be configured for full-duplex operation. In addition, different types of full-duplex communication may be associated with corresponding resource configurations, which may include uplink and downlink resources that overlap in the time domain and frequency domain (e.g., in-band full-duplex), or uplink and downlink resources that overlap in the time domain but are separated by a guard band in the frequency domain (e.g., sub-band full-duplex). A wireless device that supports full-duplex may use one or more of these full-duplex communication types and corresponding resource configurations.

[0047] In some cases, a wireless device supporting full-duplex communication may be affected by self-interference caused by signal leakage between a transmit antenna array and a receive antenna array. For example, a UE supporting full-duplex communication may experience interference from its own uplink transmission on its receive antenna (e.g., when transmitting in the uplink and receiving in the downlink at the same time). Additionally or alternatively, a base station may configure the UE with full-duplex communication resources for a set of time slots. The base station may then determine that one or more resources are not available for communication by the UE. In some wireless communication systems, a base station may send a downlink preemption indication to indicate to the UE some resources in which downlink transmission is absent (e.g., resources canceled by the base station after the UE is configured with downlink communication resources). Similarly, a base station may send an uplink preemption indication to indicate to the UE some resources in which uplink resources have been canceled by the base station.

[0048] Typically, downlink preemption indication and uplink preemption indication are sent via separate downlink control information messages, and may include more resources. As described herein, full-duplex UE can support simultaneous downlink and uplink communications, and can be configured with overlapping (completely or partially overlapping) uplink communication resources and downlink communication resources. Therefore, in order to reduce the amount of resources when notified by signaling, there is a demand for a shared preemption indication for full-duplex UE, so that both downlink preemption indication and uplink preemption indication need a shared preemption indication.

[0049] As described herein, various techniques and configurations can enhance full-duplex communication in a network, further reduce the amount of resources and improve the efficiency of UEs. As an example, a base station may send a configuration of full-duplex communication resources for a UE for a time slot set to a UE. In order to indicate a downlink preemption indication and an uplink preemption indication for a time slot set configured with full-duplex communication resources, the base station may signal the UE (e.g., via a downlink control information message or sequence) a full-duplex preemption indication. According to one or more aspects of the present disclosure, a UE may receive a full-duplex preemption indication, and may identify downlink preemption resources and uplink cancellation resources based on the full-duplex preemption indication. The UE may then determine the remainder of the full-duplex communication resources, and may use the remainder to communicate with the base station.

[0050] Features of the subject matter described herein may be implemented to achieve one or more advantages. Among other advantages, the techniques may generally support improvements to full-duplex communications, as well as enhancements to reliability and interference cancellation. Thus, the supported techniques may include improved network operation, and in some examples, may improve network efficiency, improve spectral efficiency, and enable low-latency reliable communications, among other benefits.

[0051] Aspects of the disclosure are initially described in the context of wireless communication systems. Aspects of the disclosure are described in the context of resource configurations and processes. Aspects of the disclosure are further illustrated and described through apparatus diagrams, system diagrams, and flow diagrams with preemption indication for full-duplex communications.

[0052] Figure 1The diagram illustrates an example of a wireless communication system 100 that supports preemptive indication for full-duplex communication in accordance with aspects of the present disclosure. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low-latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0053] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may be devices of different forms or with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base stations 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 may support communication of signals according to one or more radio access technologies.

[0054] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be fixed or mobile, or both at different times. The UEs 115 may be devices of different forms or with different capabilities. Figure 1 Some exemplary UEs 115 are illustrated in FIG. Figure 1 As shown, the UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices).

[0055] The base stations 105 may communicate with the core network 130, or with each other, or both. For example, the base stations 105 may interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate with each other via the backhaul links 120 (e.g., via X2, Xn, or other interfaces) directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130), or both. In some examples, the backhaul links 120 may be or may include one or more wireless links.

[0056] The one or more base stations 105 described herein may include or may be referred to by a person of ordinary skill in the art as a base station transceiver, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next generation NodeB or a giga-NodeB (any of which may be referred to as a gNB), a Home NodeB, a Home eNodeB, or other suitable terminology.

[0057] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0058] like Figure 1 As shown, the UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc.

[0059] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more physical layer channels of a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0060] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located based on a channel raster for discovery by UE 115. A carrier may operate in a standalone mode, in which initial acquisition and connection may be performed by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which another different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0061] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry either downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry both downlink communications and uplink communications (e.g., in TDD mode).

[0062] A carrier may be associated with a particular bandwidth of a radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a plurality of determined bandwidths of a carrier for a radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). A device of the wireless communication system 100 (e.g., a base station 105, a UE 115, or both) may have a hardware configuration that supports communication on a carrier bandwidth, or may be configured to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or a UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, a BWP) or all of a carrier bandwidth.

[0063] The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource unit may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource unit may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource units received by UE 115 and the higher the order of the modulation scheme, the higher the data rate for UE 115 can be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further improve the data rate or data integrity of communications with UE 115.

[0064] One or more digital schemes for a carrier may be supported, where the digital scheme may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs with the same or different digital schemes. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications for a UE 115 may be limited to the one or more active BWPs.

[0065] The time interval for the base station 105 or the UE 115 may be expressed as a multiple of a basic time unit. For example, the basic time unit may be T s =1 / (Δf max ·N f ) seconds sampling period, where Δf max It can represent the maximum subcarrier spacing supported, N f The maximum supported discrete Fourier transform (DFT) size may be indicated. The time intervals of the communication resources may be organized according to radio frames, each radio frame having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0066] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a number of small time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0067] A subframe, a time slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a short TTI (sTTI)).

[0068] Physical channels can be multiplexed on a carrier according to various techniques. For example, physical control channels and physical data channels can be multiplexed on a downlink carrier using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. The control region (e.g., a control resource set (CORESET)) of a physical control channel can be defined by a number of symbol periods and can extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) can be configured for a group of UEs 115. For example, one or more UEs 115 in the UE 115 can monitor or search the control region to obtain control information according to one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of the control channel candidate can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information of the control information format with a given payload size. The search space sets may include a common search space set configured for transmitting control information to a plurality of UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0069] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with the base station 105 (e.g., via a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) used to distinguish adjacent cells. In some examples, a cell may also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors such as the capabilities of the base station 105, the cell may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell may be or may include a building, a subset of a building, or an external space between or overlapping geographic coverage areas 110, and the like.

[0070] A macro cell may typically cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs 115 that have signed a service contract with a network provider that supports the macro cell. Small cells may be associated with base stations 105 with lower power than macro cells, and small cells may operate in the same or different frequency bands (e.g., licensed, unlicensed) as macro cells. Small cells may provide unrestricted access to UEs 115 that have signed a service contract with a network provider, or may provide restricted access to UEs 115 associated with small cells (e.g., UEs 115 in a closed user group (CSG), UEs 115 associated with users in a home or office). A base station 105 may support one or more cells, and may also support communication on one or more cells using one or more component carriers.

[0071] In some examples, a carrier can support multiple cells, and different cells can be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)), which can provide access to different types of devices.

[0072] In some examples, base stations 105 may be mobile and, therefore, provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0073] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timing, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timing, and in some examples, transmissions from different base stations 105 may not be aligned in time. The techniques described herein may be used for either synchronous operation or asynchronous operation.

[0074] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automatic communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents the information to a person interacting with the application. Some UEs 115 may be designed to collect information or implement automatic behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.

[0075] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception simultaneously). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for UE 115 include entering a power saving deep sleep mode when not engaged in active communications, operating over a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0076] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE115 can be designed to support ultra-reliable, low-latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication or group communication, and can be supported by one or more mission-critical services, such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions can include: priority treatment of services, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency can be used interchangeably in this article.

[0077] In some examples, the UE 115 may also be able to communicate directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be located within a geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105, or may be unable to receive transmissions from the base station 105 for other reasons. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0078] In some systems, the D2D communication link 135 can be an example of a communication channel (e.g., a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these communications. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in a V2X system can communicate with roadside infrastructure (e.g., roadside units) using vehicle-to-network (V2N) communication, or communicate with the network via one or more network nodes (e.g., base station 105), or both.

[0079] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connection, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity for managing access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity for routing packets or interconnections to an external network (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by a base station 105 associated with the core network 130. User IP packets may be delivered through user plane entities, which may provide IP address allocation and other functions. The user plane entity may be connected to a network operator IP service 150. The operator IP service 150 may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.

[0080] Some network devices (e.g., base stations 105) may include subcomponents, such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs), or merged into a single network device (e.g., base station 105).

[0081] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range is approximately 1 decimeter to 1 meter. UHF waves may be blocked or redirected by buildings and environmental features, but these waves may be sufficient to penetrate structures so that macro cells provide service to UEs 115 located indoors. Transmissions using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than transmissions using smaller frequencies and longer wavelengths in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0082] The wireless communication system 100 may also operate in a super high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz, also known as a centimeter band, or in an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz), also known as a millimeter band. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and base station 105, and the EHF antennas of each device may be smaller and closer than UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be affected by greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein may be used across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary by country or regulatory agency.

[0083] The wireless communication system 100 can use licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 can use licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed radio frequency spectrum band, devices such as base stations 105 and UEs 115 can use carrier sensing for conflict detection and avoidance. In some examples, operations in unlicensed bands can be based on a carrier aggregation configuration combined with component carriers operating in a licensed band (e.g., LAA). Operations in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and the like.

[0084] The base station 105 or UE 115 may be equipped with multiple antennas that may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that may support MIMO operations or transmit beamforming or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array that has several rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals sent via the antenna ports.

[0085] The base station 105 or UE 115 can use MIMO communication to exploit multipath signal propagation, and can improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such technology can be referred to as spatial multiplexing. For example, the multiple signals can be sent by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) and multi-user MIMO (MU-MIMO), in which multiple spatial layers are sent to the same receiving device and in which multiple spatial layers are sent to multiple devices.

[0086] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals transmitted via antenna elements of an antenna array so that some signals propagating in one or more directions relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals transmitted via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals transmitted via antenna elements associated with the device. Adjustments associated with each antenna element may be defined by a set of beamforming weights associated with a direction (e.g., a direction relative to an antenna array of the transmitting device or the receiving device, or a direction relative to some other direction).

[0087] The base station 105 or the UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communications with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the base station 105 in different directions. For example, the base station 105 may send signals based on different sets of beamforming weights associated with different transmit directions. Transmissions in different beam directions may be used to identify (e.g., by a transmitting device (e.g., the base station 105), or by a receiving device (e.g., the UE 115)) the beam direction for the base station 105 to transmit or receive later.

[0088] Some signals, such as data signals associated with a receiving device, may be sent by base station 105 in a single beam direction (e.g., a direction associated with a receiving device, such as UE 115). In some examples, a beam direction associated with transmissions along a single beam direction may be determined based on signals that have been sent in one or more beam directions. For example, UE 115 may receive one or more of the signals sent by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0089] In some examples, transmissions by a device (e.g., base station 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across a system bandwidth or one or more subbands. Base station 105 may send reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)), which may be precoded or not precoded. UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals sent by base station 105 in one or more directions, UE 115 may employ similar techniques to send signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by UE 115), or to send signals in a single direction (e.g., for sending data to a receiving device).

[0090] When receiving various signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) from the base station 105, the receiving device (e.g., UE 115) can try multiple reception configurations (e.g., directional listening). For example, the receiving device can try multiple reception directions by receiving via different antenna subarrays, by processing the received signal according to different antenna subarrays, by receiving according to different reception beamforming weight sets applied to the signal received at multiple antenna elements of the antenna array (e.g., different directional listening weight sets), or by processing the received signal according to different reception beamforming weight sets applied to the signal received at multiple antenna elements of the antenna array; according to different reception configurations or reception directions, any of which can be referred to as "listening". In some examples, the receiving device can use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). The single reception configuration can be aligned on a beam direction determined based on listening according to different reception configuration directions (e.g., based on a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening to multiple beam directions).

[0091] The wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, the communication at the bearer or packet data aggregation protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly to communicate through logical channels. The medium access control (MAC) layer may perform priority processing and multiplexing of logical channels to transport channels. The MAC layer may also support retransmission at the MAC layer using error detection techniques, error correction techniques, or both to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration, and maintenance of an RRC connection supporting radio bearers for user plane data between the UE 115 and the base station 105 or the core network 130. At the physical layer, transport channels may be mapped to physical channels.

[0092] UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data through communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support simultaneous slot HARQ feedback, in which a device may provide HARQ feedback in a particular time slot for data received in a previous symbol in the time slot. In other cases, a device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0093] Existing wireless communication systems may not be able to use a common preemption indication for full-duplex communication. For example, in an existing wireless communication system, a downlink preemption indication may be defined as indicating some resources in which a downlink transmission is absent (e.g., the downlink transmission was previously configured by a base station, but subsequently cancelled by the base station after configuring the UE). Similarly, an uplink preemption indication is defined as indicating some resources in which the uplink resources were previously configured by a base station, but subsequently cancelled by the base station. Some wireless communication systems typically provide transmission of downlink preemption indications and uplink preemption indications by separate indications (e.g., via separate downlink control information messages), and may use more resources. A UE supporting full-duplex communication may support simultaneous downlink and uplink communications (e.g., parallel communications on a downlink and an uplink). A full-duplex UE may be configured with overlapping (completely or partially overlapping) uplink communication resources and downlink communication resources. However, separately providing downlink preemption indications and uplink preemption indications may be time-consuming, may result in high overhead signaling costs, and may use a large amount of computing processing resources.

[0094] One or more aspects of the present disclosure provide a shared preemption indication (e.g., a full-duplex preemption indication) for a full-duplex UE, so that the shared preemption indication uses fewer resources and improves the efficiency of the UE. In some examples, the base station 105 may send a configuration of full-duplex communication resources for the UE 115 for a set of time slots. The UE 115 may identify the full-duplex communication resources based on receiving the configuration. The UE 115 may then receive a preemption indication from the base station 105. The preemption indication may identify that at least a portion of the full-duplex communication resources in one or more time slots of the time slot set are not available for communication with the UE 115. Based on the preemption indication, the UE 115 may determine the remaining portion of the full-duplex communication resources in the one or more time slots, and may use the remaining portion of the full-duplex communication resources to communicate with the base station 105. Therefore, as described herein, the results that can be achieved by providing a shared preemption indication are improved throughput, improved system efficiency, and improved user experience.

[0095] Figure 2 The figure illustrates an example of a wireless communication system 200 that supports preemption indication for full-duplex communication according to aspects of the present disclosure. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. The wireless communication system 200 may include UE 115-a, UE 115-b, base station 105-a, and base station 105-b, which may be reference Figure 1 Examples of corresponding devices described. In some cases, the wireless communication system 200 (e.g., a 5G or NR system) can support enhancements to full-duplex communication at both ends of the communication link (e.g., for both the UE 115 and the base station 105).

[0096] In some cases, the UE 115-a and the base station 105-a may support full-duplex communication on the uplink communication link 205. When full-duplex communication is used to send and receive signals, the UE 115-a or the base station 105-a or both may experience self-interference due to sending and receiving signals. In some examples, the UE 115-a or the base station 105-a or both may experience self-interference due to communicating using spatially close antenna arrays. For example, the UE 115-a may send a signal to the base station 105-a on the uplink communication link 205-a via a transmit antenna array, while receiving a signal from the base station 105-a on the downlink communication link 210-a via a receive antenna array. In the case where the transmit antenna array is spatially close to the receive antenna array, the UE 115-a may be subject to interference at the receive antenna array from transmissions via the transmit antenna array. Specifically, UE 115 - a may experience interference on its receive antenna from its own uplink transmissions (eg, when simultaneously transmitting in the uplink and receiving in the downlink).

[0097] In some examples, UE 115-a may experience cross-link interference from uplink transmissions of nearby or neighboring UEs 115 (e.g., uplink transmissions of UE 115-b on uplink communication link 205-b may produce an interfering signal (e.g., on communication link 220-a)). In some examples, UE 115-a may experience cross-link interference on communication link 220-c, and base station 105-a may experience cross-link interference on communication link 220-b. Base station 105-a may experience self-interference for similar reasons. For example, when receiving uplink communications from one or more UEs 115 (e.g., including UEs 115-a and 115-b) while simultaneously communicating to UE 115-a on a downlink, base station 105-a may experience self-interference, where the downlink signal transmission may cause self-interference to reception on the uplink at base station 105-a. Additionally, base station 105 - a may experience cross-link interference from base station 105 - b (eg, on communication link 220 - d ).

[0098] Additionally or alternatively, based on simultaneous communication via uplink communication link 205-b and downlink communication link 210-b, a similar situation can be applied to UE 115-b and base station 105-b on downlink communication link 210. In some examples, UE 115-a can identify that UE 115-a can support in-band full-duplex or sub-band full-duplex (e.g., flexible duplex) or both on uplink communication link 205. UE (e.g., UE 115-a and UE 115-b) and base station (e.g., base station 105-a and base station 105-b) can support in-band full-duplex. In in-band full-duplex, UE and base station can send and receive signals on the same time and frequency resources. That is, in in-band full-duplex, downlink and uplink share the same in-band full-duplex time or frequency resources. In some cases, in in-band full-duplex mode, downlink and uplink resources can overlap completely or partially (e.g., transmitted in the same frequency band).

[0099] Additionally or alternatively, a UE (e.g., UE 115-a and UE 115-b) and a base station (e.g., base station 105-a and base station 105-b) may support sub-band flexible duplexing. In sub-band flexible duplexing, the UE and the base station may transmit and receive simultaneously but on different frequency resources. For example, in sub-band flexible duplexing, downlink resources may be separated from uplink resources in the frequency domain. The downlink and uplink may be transmitted in different frequency bands, and a guard band may be located between the downlink resources and the uplink resources. In some examples, signal leakage between the downlink and uplink in a sub-band flexible duplexing mode may cause self-interference in the UE (e.g., UE 115-a and UE 115-b). In some examples, UE 115-a may identify one or more full-duplex communication types that UE 115-a may support on a per-frequency band basis. Thus, UE 115-a may identify one or more full-duplex communication types that UE 115-a may support at each frequency band of resources identified by UE 115-a. In one illustrative example, UE 115-a may identify that it supports intra-band full-duplex on a first number of frequency bands, supports sub-band full-duplex on a second number of frequency bands, and supports both intra-band full-duplex and sub-band full-duplex on a third number of frequency bands.

[0100] In a wireless communication system supporting NR, a downlink preemption indication may be defined to indicate to a UE (e.g., UE 115-a and UE 115-b) some resources in which downlink transmission is absent (e.g., downlink transmission is cancelled by a base station after the UE is configured). That is, a downlink preemption indication may be defined to indicate to the UE some resources at which the UE does not consider any downlink transmission. In one example, the downlink preemption indication may be indicated by a physical downlink control channel (as part of a downlink control information message). In some wireless communication systems, a UE (e.g., UE 115-a and UE 115-b) may receive a downlink preemption indication by periodically monitoring a radio network temporary identifier. Similarly, an uplink preemption indication may be defined to indicate to a UE (e.g., UE 115-a and UE 115-b) some resources in which uplink resources have been cancelled by a base station (e.g., base station 105-a and base station 105-b). In some examples, there may be different priorities assigned to different UEs. If a high priority UE needs resources, the base station can cancel the low priority resources to serve the high priority resources. The downlink preemption indication and the uplink preemption indication can be effectively used for inter-user interference management. That is, the downlink preemption indication and the uplink preemption indication can provide high reliability in the communication between the UE and the base station.

[0101] In some wireless communication systems, downlink preemption indication and uplink preemption indication may be sent via separate downlink control information messages, and thus may use a large amount of resources. A full-duplex UE may support simultaneous downlink and uplink communications, and thus may be configured with overlapping (complete or partial) uplink communication resources and downlink communication resources. There is a need for a shared preemption indication (e.g., full-duplex preemption indication) for a full-duplex UE, so that the shared preemption indication uses fewer resources and improves the efficiency of the UE.

[0102] As described herein, UE 115-a, UE 115-b, base station 105-a, and base station 105-b may implement a method for providing a common preemption indication during full-duplex communication. Although examples are provided in the context of full-duplex communication between UE 115-a and base station 105-a on uplink communication link 205, the described techniques are equally applicable to UE 115-b and base station 105-b on downlink communication link 210. In addition, the techniques described herein are not limited to communication between UE 115 and base station 105, and may be applied to any two communication devices that can support full-duplex communication.

[0103] According to one or more aspects of the present disclosure, a full-duplex UE (e.g., UE 115-a) may interpret a downlink preemption indication as an uplink preemption based on the indicated resources. Similarly, UE 115-a may interpret an uplink preemption indication as a downlink preemption based on the indicated resources. In some aspects of full-duplex communication, the downlink and uplink may use the same resources (e.g., time or frequency resources). In some examples, interpreting a downlink preemption indication as an uplink preemption and vice versa may reduce self-interference at UE 115-a. Additionally or alternatively, base station 105-a may send a downlink preemption indication and / or an uplink preemption indication to reduce cross-link interference. In some examples, UE 115-a may receive a downlink preemption indication and / or an uplink preemption indication in a full-duplex time slot and interpret it in a time division duplex time slot.

[0104] To indicate downlink and uplink preemption indications for a full-duplex time slot, the base station 105-a may signal the full-duplex preemption indication to the UE 115-a (e.g., via a downlink control information message or sequence). According to one or more aspects, the UE 115-a may identify downlink preemption resources and uplink cancellation resources based on the full-duplex preemption indication. The UE 115-a may then determine the remainder of the full-duplex communication resources. For example, in response to receiving the full-duplex preemption indication, the UE 115-a may determine that the downlink resources indicated by the full-duplex preemption indication are considered downlink preemption indications, while the uplink resources are considered uplink preemption indications. The UE 115-a may then communicate using the remainder of the full-duplex communication resources.

[0105] According to one or more aspects, the base station 105-a can avoid sending additional downlink or uplink preemption indications (i.e., in addition to the full-duplex preemption indications) in a set of time slots configured for full-duplex communication. In some examples, the base station 105-a can send additional downlink or uplink preemption indications (e.g., for higher reliability, higher preemption resolution, or more preemption resources). Upon receiving the additional downlink or uplink preemption indications, the UE 115-a can identify the corresponding downlink or uplink resources that are not available for communication. Alternatively, upon receiving the additional downlink or uplink preemption indications, the UE 115-a can assume that there are no additional downlink or uplink preemption indications.

[0106] Figure 3 The diagram illustrates an example of a resource configuration 300 that supports preemption indication for full-duplex communication according to aspects of the present disclosure. In some examples, the resource configuration 300 can implement various aspects of the wireless communication system 100 and the wireless communication system 200. For example, the resource configuration 300 can be configured by the base station 105 (e.g., reference Figure 2 The base station 105-a described herein may be configured to receive a signal from a UE 115 (eg, UE 115-a, as described in reference Figure 2 In such examples, resource configuration 300 may be an example of a resource configuration that may be used by UE 115 and base station 105 to support full-duplex communication, which may support full-duplex preemption indication to reduce or mitigate self-interference of one or more devices.

[0107] As described herein, UE 115 and base station 105 may support full-duplex communication using one or more full-duplex communication types. For example, UE 115 may identify one or more full-duplex communication types for each frequency band within the resources identified by UE 115. For example, UE 115 may identify resources for full-duplex communication with base station 105. One or more frequency bands may be included within the resources identified by UE 115, and each frequency band may be associated with a full-duplex communication type that UE 115 may support. In some examples, base station 105 may configure resource configurations, such as resource configuration 300, for UE 115. UE 115 and base station 105 may transmit and / or receive simultaneously on uplink resources 310 and downlink resources 305 based on the resource configurations.

[0108] In some examples, UE 115 can support intra-band full-duplex for one or more frequency bands. The one or more frequency bands can include uplink resources 310 and downlink resources 305. Resource configuration 300 can illustrate that UE 115 and base station 105 communicate using completely overlapping resources of uplink resources 310 and downlink resources 305 (e.g., providing overlapping time and frequency resources for both uplink resources 310 and downlink resources 305).

[0109] According to one or more aspects of the present disclosure, the base station 105 may send a full-duplex preemption indication defined for a full-duplex UE. In one option, the full-duplex preemption indication may include downlink preemption resources and uplink cancellation resources separately. In another option, the full-duplex preemption indication may include downlink resources or uplink resources, and the base station may send another indication (e.g., a downlink control information message) to identify whether the resource is a downlink resource or an uplink resource. In a third option, the full-duplex preemption indication may include downlink resources, uplink resources, and resources shared by downlink and uplink.

[0110] In some cases, UE 115 may receive a configuration of full-duplex communication resources for UE 115 for a set of time slots. Figure 3As shown, UE 115 can identify resources of uplink resources 310 and resources of downlink resources 305 based on the received configuration. UE 115 can then receive a preemption indication (e.g., a full-duplex preemption indication) from base station 105. The preemption indication can be included at least in a sequence, a physical downlink control channel, or a combination thereof. In some examples, the period of the preemption indication corresponds to a period of the multiple time slots. According to some aspects, the preemption indication can identify that at least a portion of the full-duplex communication resources in one or more time slots of the multiple time slots are not available for communication with UE 115. In some examples, UE 115 can determine the remaining portion of the full-duplex communication resources in the one or more time slots based on the received preemption indication. As shown in FIG. Figure 3 As shown in the example of , the preemption indication may indicate that the unavailable resources 315 are unavailable for communication by the UE 115. In one example, the preemption indication may separately indicate uplink resources that are unavailable for communication within the resources of the uplink resources 310 and downlink resources that are unavailable for communication within the resources of the downlink resources 305. For example, the UE 115 may determine that the received preemption indication identifies that at least a portion of the downlink communication resources and at least a portion of the uplink communication resources in the one or more time slots are unavailable for communication with the UE. In some cases, the received preemption indication includes a downlink preemption indication or an uplink preemption indication (which is indicated via a downlink control information message).

[0111] Additionally or alternatively, the preemption indication may indicate some resources, and the interpretation at the UE 115 may be implicit or explicit. For example, the UE 115 may determine that the received preemption indication includes a first indication and a second indication. The UE 115 may determine that the first indication identifies that at least a portion of the downlink resources 305 in the one or more time slots are not available for communication with the UE, and the second indication identifies that at least a portion of the uplink resources 310 in the one or more time slots are not available for communication with the UE. Figure 3 As described in the example of , the unavailable resources 315 may include at least a portion of the downlink resources 305 and at least a portion of the uplink resources 310. After sending the preemption indication, the base station 105 may send a second indication (e.g., a bit in a downlink control information message) indicating whether the resources indicated by the preemption indication include downlink resources or uplink resources.

[0112] According to one or more aspects, the preemption indication may indicate unavailable downlink resources and unavailable uplink resources and resources shared by uplink and downlink. For example, UE 115 may receive a preemption indication indicating at least one of a first resource set, a second resource set, a third resource set, or a combination thereof. In some examples, the first resource set may include uplink communication resources, the second resource set may include downlink communication resources, and the third resource set may include resources shared by uplink communication and downlink communication. Figure 3 As described in the example of , the unavailable resources 315 may include at least a portion of the downlink resources 305 , at least a portion of the uplink resources 310 , and at least a portion of the resources shared by the downlink resources 305 and the uplink resources 310 .

[0113] In some aspects, the preemption indication may indicate unavailable resources 315, and the UE may interpret the downlink preemption resources in the downlink bandwidth and the uplink preemption resources in the uplink bandwidth. For example, after identifying the unavailable resources 315, the UE 115 may determine a first subset of the portion of the downlink resources 305 and a second subset of the portion of the uplink resources 310. The first subset and the second subset may be overlapping or non-overlapping subsets. In some cases, the size of the downlink communication resources may correspond to the bandwidth portion associated with the downlink communication, and the size of the uplink communication resources may correspond to the bandwidth portion associated with the uplink communication.

[0114] In some cases, the period of preemptive indication can be associated with the period of full-duplex time slots. In some examples, if UE 115 determines that the number of full-duplex time slots is less than the threshold number of time slots (e.g., 1 time slot), UE 115 can assume that there is no preemptive indication. Alternatively, if UE 115 determines that the number of full-duplex time slots meets the threshold number of time slots, UE 115 can periodically receive the preemptive indication. In some examples, according to the reliability and detection complexity at UE 115, the format of the preemptive indication can take different forms. In some examples, the difference between the timing associated with receiving the preemptive indication and the timing associated with the uplink communication resource included in the part of the full-duplex communication resource in the one or more time slots meets the threshold. That is, UE 115 can receive the preemptive indication including the downlink preemptive indication after receiving the downlink resource 305. In some cases, the UE 115 may receive a preemption indication including an uplink preemption indication prior to the cancelled uplink resources to allow time for the UE 115 to cancel the uplink resources 310 .

[0115] Figure 4The diagram illustrates an example of a resource configuration 400 that supports preemption indication for full-duplex communication according to aspects of the present disclosure. In some examples, the resource configuration 400 can implement various aspects of the wireless communication system 100 and the wireless communication system 200. For example, the resource configuration 400 can be configured by the base station 105 (e.g., reference Figure 2 The base station 105-a described herein may be configured to receive a signal from a UE 115 (eg, UE 115-a, as described in reference Figure 2 In such examples, resource configuration 400 may be an example of a resource configuration that may be used by UE 115 and base station 105 to support full-duplex communication, which may support full-duplex preemption indication to reduce or mitigate self-interference of one or more devices.

[0116] As described herein, UE 115 and base station 105 may support full-duplex communication using one or more full-duplex communication types. For example, UE 115 may identify one or more full-duplex communication types for each frequency band within the resources identified by UE 115. For example, UE 115 may identify resources for full-duplex communication with base station 105. One or more frequency bands may be included within the resources identified by UE 115, and each frequency band may be associated with a full-duplex communication type that UE 115 may support. In some examples, base station 105 may configure resource configurations, such as resource configuration 400, for UE 115. UE 115 and base station 105 may transmit and / or receive simultaneously on uplink resources 410 and downlink resources 405 based on the resource configurations.

[0117] In some examples, UE 115 can support in-band full-duplex, and base station 105 can configure resource configuration 400 for simultaneous transmission on uplink resources 410 and downlink resources 405. Resource configuration 400 can be an example in which resources provided for uplink resources 410 and downlink resources 405 can at least partially overlap. In such examples, uplink resources 410 and downlink resources 405 can share a first portion of their frequency allocations and can dedicate a second portion of their frequency allocations to uplink and downlink communications.

[0118] According to one or more aspects of the present disclosure, UE 115 may receive a configuration of full-duplex communication resources for UE 115 for a set of time slots. Figure 4As shown in , UE 115 can identify uplink resources 410 and downlink resources 405 based on the received configuration. According to one or more aspects, base station 105 can send a full-duplex preemption indication defined for a full-duplex UE after sending the configuration. In some examples, the full-duplex preemption indication can separately include downlink preemption resources and uplink cancellation resources. For example, the preemption indication can identify that at least a portion of the full-duplex communication resources in one or more time slots of the multiple time slots are not available for communication with UE 115. In some cases, UE 115 can determine the remaining portion of the full-duplex communication resources in the one or more time slots based on the received preemption indication. As shown in FIG. Figure 4 As shown in the example of , the preemption indication may indicate that resources 415 are not available for communication by UE 115 .

[0119] As reference Figure 3 As further described, the preemption indication may separately indicate uplink resources that are unavailable for communication within the uplink resources 410 and downlink resources that are unavailable for communication within the downlink resources 405. In another example, the UE 115 may determine that the received preemption indication includes a first indication and a second indication, the first indication indicating that at least a portion of the downlink resources 405 in the one or more time slots are unavailable for communication with the UE, and the second indication indicating that at least a portion of the uplink resources 410 in the one or more time slots are unavailable for communication with the UE. In another example, the preemption indication may indicate unavailable downlink resources and unavailable uplink resources as well as resources shared by the uplink and downlink. Figure 4 As described in the example of , the unavailable resources 415 may include at least a portion of the downlink resources 405, at least a portion of the uplink resources 410, and at least a portion of the resources shared by the downlink resources 405 and the uplink resources 410. Figure 3 Additional or alternative implementations of the illustrated preemption indications may also be applied to resource configuration 400 .

[0120] Figure 5 The diagram illustrates an example of a resource configuration 500 that supports preemption indication for full-duplex communication according to aspects of the present disclosure. In some examples, the resource configuration 500 can implement aspects of the wireless communication system 100 and the wireless communication system 200. For example, the resource configuration 500 can be configured by the base station 105 (e.g., reference Figure 2 The base station 105-a described herein may be configured to receive a signal from a UE 115 (eg, UE 115-a, as described in reference Figure 2In such examples, resource configuration 500 may be an example of a resource configuration that UE 115 and base station 105 may use to support full-duplex communication, which may support full-duplex preemption indication to reduce or mitigate self-interference of one or more devices.

[0121] As described herein, UE 115 and base station 105 can support full-duplex communication using one or more full-duplex communication types. In some examples, base station 105 can configure resource configurations for UE 115, such as resource configuration 500. UE 115 and base station 105 can simultaneously send and / or receive uplink 510 and downlink 505 based on the resource configuration.

[0122] In some examples, UE 115 may support sub-band full-duplex for each of a number of frequency bands included in the resources identified by UE 115 for full-duplex communication. In such examples, base station 105 may configure resource configuration 500. Resource configuration 500 may illustrate an example in which uplink 510 and downlink 505 may be simultaneously transmitted but may use different frequency resources. In some examples, the base station may separate the frequency resources provided for each of uplink 510 and downlink 505 by guard band 520 (e.g., uplink 510 and downlink 505 may be associated with different bandwidth portions). In some examples, by identifying frequency resources (e.g., one or more frequency bands) that support sub-band full-duplex, UE 115 may reduce self-interference by using two different frequencies for transmission and reception.

[0123] The guard band 520 may be a frequency range that separates the frequencies used for the uplink 510 and the downlink 505, and may be included in the resource configuration 500 by the base station 105 based on identifying that the UE 115 supports sub-band full-duplex. The base station 105 may define (e.g., configure) the guard band 520 (e.g., may determine the guard band configuration) based on a number of different characteristics of full-duplex communication. In some cases, the guard band configuration may indicate a number of resource blocks (e.g., physical resource blocks) and / or a number of resource units for the guard band. That is, the guard band 520 may be defined based on physical resource blocks and / or resource units via the guard band configuration.

[0124] As reference Figure 3 and 4As described, UE 115 may receive a configuration of full-duplex communication resources for UE 115 for a set of time slots. UE 115 may identify resources for uplink 510 and resources for downlink 505 based on the received configuration. According to one or more aspects, base station 105 may send a full-duplex preemption indication defined for a full-duplex UE after sending the configuration. In some examples, the full-duplex preemption indication may separately include downlink preemption resources and uplink cancellation resources. For example, the preemption indication may identify that at least a portion of the full-duplex communication resources in one or more time slots of the plurality of time slots are not available for communication with UE 115. In some cases, UE 115 may determine the remaining portion of the full-duplex communication resources in the one or more time slots based on the received preemption indication. As described in detail in FIG. Figure 5 As shown in the example of , the preemption indication may indicate that resource 515 is not available for communication with UE 115. It is understood that, as shown in FIG. Figure 3 and 4 Additional or alternative implementations of the illustrated preemption indications may also be applied to resource configuration 500 .

[0125] Figure 6 The diagram illustrates an example of a process 600 for supporting preemption indication for full-duplex communication according to aspects of the present disclosure. In some examples, the process 600 can be implemented with reference to Figure 1 and Figure 2 Various aspects of the wireless communication systems 100 and 200 described herein may be described. For example, the process 600 may be based on a signaling process for indicating full-duplex preemption indication from the base station 105-c and the UE 115-c. The process 600 may be implemented by the UE 115-c and the base station 105-c to reduce power consumption and may promote low latency in wireless communication, among other benefits. The base station 105-c and the UE 115-c may be reference Figure 1 and 2 In the following description of process 600, the operations between base station 105-c and UE 115-c may be sent in an order different from the exemplary order shown, or the operations performed by base station 105-c and UE 115-c may be performed in a different order or at a different time. Some operations may also be omitted from process 600, and other operations may be added to process 600.

[0126] At 605, the UE 115-c may receive a configuration of full-duplex communication resources for the UE 115-c for a set of time slots. At 610, the UE 115-c may identify the full-duplex communication resources based on receiving the configuration. In some examples, the full-duplex communication resources may include downlink resources and uplink resources.

[0127] At 615, the base station 105-c may identify a first indication and a second indication. In some examples, the first indication may identify that at least a portion of downlink communication resources in one or more time slots are not available for communication with the UE 115-c, and the second indication may identify that at least a portion of uplink communication resources in one or more time slots are not available for communication with the UE 115-c. The base station 105-c may include the first indication and the second indication in a full-duplex preemption indication.

[0128] At 620, UE 115-c may receive a preemption indication from base station 105-c, the preemption indication identifying that at least a portion of full-duplex communication resources in one or more time slots in the time slot set are not available for communication with UE 115-c. For example, a preemption indication (e.g., a full-duplex preemption indication) may be defined as indicating to UE 115-c some resources in which downlink transmission is absent or some resources in which base station 105-c has canceled uplink resources. In some cases, the period of the preemption indication may correspond to the period of the time slot set. Additionally or alternatively, base station 105-c may include the preemption indication in a sequence or physical downlink control channel. In some examples, the preemption indication may be explicitly transmitted, such as by one or more bits in a DCI. In other examples, the preemption indication may be implicitly transmitted, such as by a specific arrangement or combination of bits in the DCI that should be used to transmit other information. Such a DCI may authorize one or more sets of uplink communication resources, one or more sets of downlink communication resources, or a combination of these resources.

[0129] At 625, the UE 115-c may determine a remaining portion of the full-duplex communication resources in the one or more time slots based on the received preemption indication. For example, the UE 115-c may determine that the unavailable portion of the full-duplex communication resources in the one or more time slots includes downlink communication resources. Additionally or alternatively, the UE 115-c may determine that the unavailable portion of the full-duplex communication resources in the one or more time slots includes uplink communication resources.

[0130] At 630, optionally, the UE 115-c may receive a second preemption indication from the base station 105-c. In some examples, the second preemption indication may include a downlink preemption indication or an uplink preemption indication. In some examples, the UE 115-c may determine a remaining portion of the full-duplex communication resources in the one or more time slots based on the received preemption indication and the received second preemption indication. Alternatively, the UE 115-c may assume that the second preemption indication is not present based on the received preemption indication and the received second preemption indication.

[0131] At 635, the UE 115-c may communicate with the base station 105-c using the remaining portion of the full-duplex communication resources.

[0132] The operations performed by the base station 105-c and the UE 115-c as part of (but not limited to) the process 600 can improve full-duplex communication based on full-duplex preemption indication transmission. In addition, the operations performed by the base station 105-c and the UE 115-c as part of (but not limited to) the process 600 can provide benefits and enhancements to the operation of the UE 115-c. For example, the full-duplex preemption indication transmission operations described in the process 600 can support reduced power consumption, improved efficiency, and other advantages.

[0133] Figure 7 A block diagram 700 of a device 705 supporting preemption indication for full-duplex communication according to aspects of the present disclosure is shown. The device 705 can be an example of various aspects of the UE 115 as described herein. The device 705 may include a receiver 710, a communication manager 715, and a transmitter 720. The device 705 may also include one or more processors, a memory coupled to the one or more processors, and instructions stored in the memory, the instructions being executable by the one or more processors to enable the one or more processors to perform the features of preemption indication for full-duplex communication discussed herein. Each of these components can communicate with each other (e.g., via one or more buses).

[0134] The receiver 710 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels associated with preemption indications for full-duplex communications, data channels and information, etc.). The information may be communicated to other components of the device 705. The receiver 710 may be a reference Fig.10 Examples of various aspects of the transceiver 1020 are described. The receiver 710 may utilize a single antenna or a group of antenna receivers.

[0135] The communication manager 715 may: receive from a base station a configuration of full-duplex communication resources for a UE for a set of time slots; receive from a base station a preemption indication, the preemption indication identifying that at least a portion of the full-duplex communication resources in one or more time slots in the set of time slots are unavailable for communication with the UE; determine a remaining portion of the full-duplex communication resources in the one or more time slots based on the received preemption indication; and communicate with the base station using the remaining portion of the full-duplex communication resources. The communication manager 715 may be an example of aspects of the communication manager 1010 described herein.

[0136] The communication manager 715 or its subcomponents may be implemented in hardware, code executed by a processor (e.g., software or firmware), or any combination thereof. If implemented in code executed by a processor, the functionality of the communication manager 715 or its subcomponents may be implemented by a general purpose processor, DSP, application specific integrated circuit (ASIC), FPGA or other programmable logic device designed to perform the functions described in the present disclosure, discrete gate or transistor logic, discrete hardware components, or any combination thereof.

[0137] The communication manager 715 or its subcomponents can be physically located in various locations, including being distributed so that various portions of the functionality are implemented by one or more physical components at different physical locations. In some examples, the communication manager 715 or its subcomponents can be separate and distinct components according to aspects of the present disclosure. In some examples, according to aspects of the present disclosure, the communication manager 715 or its subcomponents can be combined with one or more other hardware components, including but not limited to input / output (I / O) components, a transceiver, a network server, another computing device, one or more other components described in the present disclosure, or a combination thereof.

[0138] The transmitter 720 can transmit signals generated by other components of the device 705. In some examples, the transmitter 720 can be co-located with the receiver 710 in a transceiver module. For example, the transmitter 720 can be a reference Fig.10 Examples of various aspects of the transceiver 1020 are described. The transmitter 720 may utilize a single antenna or a group of antennas.

[0139] Figure 8 A block diagram 800 of a device 805 supporting preemption indication for full-duplex communication according to aspects of the present disclosure is shown. The device 805 can be an example of aspects of the device 705 or UE 115 as described herein. The device 805 may include a receiver 810, a communication manager 815, and a transmitter 840. The device 805 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0140] The receiver 810 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels associated with preemption indications for full-duplex communications, data channels and information, etc.). The information may be communicated to other components of the device 805. The receiver 810 may be a reference Fig.10 Examples of various aspects of the transceiver 1020 are described. The receiver 810 may utilize a single antenna or a group of antenna receivers.

[0141] Communications manager 815 may be an example of aspects of communications manager 715 as described herein. Communications manager 815 may include configuration component 820, preemption indication component 825, resource determination component 830, and communication component 835.
